Gameplay: Arkham City is an open world action video game that incorporates elements of stealth and predator tactics. All of the gadgets previously obtained in the first game are present at the start of Arkham City (with the exception of the Line Launcher and the Ultra Batclaw, which is replaced with the regular Batclaw and Sonic Batarangs). Most of them have improved or new capabilities; for example, the Cryptographic Sequencer can also track signals, the line launcher now can be deployed as a tightrope and has a feature that allows Batman to flip over and launch another zipline, switching directions. The remote control Batarang now has a built in brake and boost, and the grappling gun can now be used while gliding to boost Batman further up into the air.
